About this sunscreen
SkinCeuticals Mineral Radiance Defense UV SPF 50 is a pure mineral sunscreen using titanium dioxide as its only UV filter. It delivers a matte, lightweight finish with low white cast, low stinging, and low breakout risk, so it is generally gentle and works well under makeup. However, relying on titanium dioxide alone limits UVA coverage, and the weak protection rating with a 49.0/100 score makes it a low-ranking choice for sun defense.
